Hunger’s maintenance-free plain bushings WGB and GB are constructed according to DIN 18550 (DIN ISO 4379) specifications. Instead of the sintered metals, non-ferrous metals, artificial carbon and duroplastic materials mentioned therein, the bushings are made of closed steel rings with PTFE based bearing layers.
Hunger plain bushings are designed for radial and axial movements and distinguish themselves by a particularly low friction coefficient without stick-slip effect.
Thanks to the strong bearing layer very long service lives can be achieved.
